HTML comments in a javascript block?

Hello im cleaning a web page from comments and other stuff.

I just found this 

I use that to comment out something on html.. but here?? look at it

<script type="text/javascript"><!--
$("ul.menubbcl").superfish({        
    animation: {height:'show'},   // slide-down effect without fade-in 
    delay:     1000,           // 1.0 second delay on mouseout
    autoArrows : true 
}); 
//--></script>

Can somebody explain me this. pls

To support very old browsers which would render the script as text in the page rather than execute it. — Michael Berkowski, Jan 14 '13 at 02:38

Funny thing: the snippet uses jQuery, but I don't think even jQuery supports such old browsers (although it probably degrades gracefully). — bfavaretto, Jan 14 '13 at 02:40
@Derek see [this answer](http://stackoverflow.com/a/5780076/781965) - `` isn't, hence the `//` beforehand. — Jeff, Jan 14 '13 at 02:52
@Derek I had a browser through the [ecma specification](http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-262.pdf) and nothing really jumped out as to why it's ok, so I suspect it's actually just that browsers can cope with it as they do with minor syntax errors, or that they know that old websites use this exact trick, so they don't complain about it. — Jeff, Jan 14 '13 at 03:22

This is for browsers that do not support Javascript. Supplying HTML comment tags around it will prevent it from being rendered as text in such browsers.
